Fields has served as the organization's minor league hitting coordinator since 2007, and was Triple-A Buffalo's hitting coach in 2006. From 2003-05, Fields was the Detroit Tigers' hitting coach.

"We are confident that Bruce Fields, who is very familiar with our current players and has a vast set of experiences coaching and preparing hitters at this level, will continue the work he has done developing our hitters at every level of the organization," Cleveland manager Manny Acta said in a release.

Fields takes over for Nunnally with the Indians struggling to score runs.

Since a 13-9 victory against Toronto on June 1, they've gone 5-11 and averaged 2.5 runs per game. They have been shut out four times over that span.

Overall, Cleveland has hit .223 with a .289 on-base percentage and .336 slugging percentage in the month of June. But the club was in first place in the AL Central prior to Sunday's game against Pittsburgh.
